Karrueche Tran has just landed herself in the middle of a bizarre love triangle with ex Chris Brown and actor/model Tyson Beckford.

Over the weekend, the Fast & Furious had the audacity to post a cute selfie in Vegas with Brown's on-again/off-again ex -- and the hot-headed rapper was having NONE of it, exploding on Twitter.

On Saturday, Beckford posted a fun snap with the petite beauty, along with the caption, "Saturday with @Karrueche #vegas #palms #blasian."

After that post, Brown had a complete meltdown, posting a slew of angry tweets and even getting some of his crew to post angry tweets. One of Brown's tweets included: "U wanna keep walking them runways. I need ta legs for that. Keep playing like I ain't wit the bulls***."

Brown wrote a plethora of other hateful tweets but has since deleted them.

Kid Red, who is a friend of Brown's, also attacked the model, writing, “MEMORIAL DAY WEEKEND aka the ni***s will be out. .. We just came to party tho , unless a ni***a wanna try us … And that includes u model ni***s “Cough Cough #TysonBeckFord, we see everything LiL n***a” #DontPlayYaSelf. #CedarBlocka#FruitTownPiru #OHB #FillmoeNi***sDoItAll@tysoncbeckford.”

Tyson had a pointed response to the hoopla. Yesterday, the 46-year-old posted a video of himself shooting a gun with the caption, "Just in case you forgot! #pewpew #nra #bang #2a #5.56 #ar15 #edc #.762."

Don't mess with Tyson!
